############################################################################## # # # ATOVS and AVHRR Preprocessing Package (AAPP) # # Version 6.5 Release Notes # # 20 Sept 2007 # # # ############################################################################## 1. Package contents ------------------- The following files are contained in this update release (with file sizes in bytes): RELEASE_NOTE_AAPP_6_5.txt 4365 This release note AAPP_update_6_5.tgz 89827 Source code and data This is an incremental update; users need to have installed version 6.1 and updates 6.2, 6.3 and 6.4. 2. Purpose ---------- The main purposes of this update are as follows: (i) NOAA-16 and NOAA-18 AMSU-A, AMSU-B and MHS quality control updates (no effect on radiance biases) (ii) Minor corrections to BUFR encode/decode (iii) Accommodate EUMETSAT-distributed NOAA-18 data (ATOVS and AVHRR) A detailed list of changed modules is given in section 5. 3. Installation --------------- 1. Copy the tgz file to your AAPP top directory (i.e. the directory containing AAPP, metop-tools and iasi-tools) 2. Unpack it using the command tar -xvmzf AAPP_update_6_5.tgz or if your system does not support the "-z" option in tar, use gunzip -c AAPP_update_6_5.tgz | tar -xmf - 3. Re-build the package using the commands cd AAPP/src/calibration/libamsuacl make clean cd ../../../.. make 4. Version control information ------------------------------ The source package (AAPP_update_6_5.tgz) corresponds to Subversion Revision 98 in the AAPP repository held at the Met Office. 5. Detailed list of changes --------------------------- Key: M=Modified, A=Added, D=Deleted M AAPP/include/amascn.h Increase maximum scans from 800 to 1000 (for full orbits) M AAPP/src/tools/libaappbufr/aapp_put_1c.F M AAPP/src/tools/libaappbufr/aapp_get_1c.F Fix AMSU-B/MHS channel numbers in BUFR encode. Improve robustness of IASI decode when there are missing times M AAPP/src/tools/libsatid/satid.txt Update mission end dates for NOAA-14 and NOAA-12 M AAPP/src/calibration/libavhrcl/avh_cpar.F M AAPP/src/calibration/libhirscl_algoV4/h_testcoeffile_algoV4.F M AAPP/src/calibration/libhirscl_algoV4/h_calibcoeffile_algoV4.F M AAPP/src/calibration/libhirscl/h_calibcoeffile.F M AAPP/src/calibration/libhirscl/h_testcoeffile.F M AAPP/src/preproc/libatovin/infdf.F M config/g95 Change open statement for g95 M config/gfortran Add -fno-range-check M AAPP/src/calibration/libamsuacl/amsua_clparams.dat M AAPP/src/calibration/libamsubcl/amsub_clparams.dat M AAPP/src/calibration/libmhscl/mhs_clparams.dat M AAPP/src/calibration/libmhscl/mhs_smpmn.F Increase tolerances for NOAA-16 AMSU-A channel 4 and NOAA-18 antenna position Update gross limits for NOAA-16 AMSU-B and NOAA-18 MHS Allow MHS calibration when ADC warning flag is set M AAPP/src/preproc/libatovin/fdf.dat Add NOAA-18 "version 2" antenna pattern corrections, as used by EUMETSAT in their global NOAA-18 relay. By default, AAPP continues to use the version 1 values. To use version 2, or to "undo" the EUMETSAT corrections, define the environment variables FDFSAT=NOAA-18, FDFVN=2 before running atovin or atovin_antcorr. M metop-tools/src/libeps_avhrrl1b_6.5/convert_avh1b.intf.c-F M metop-tools/src/libeps_avhrrl1b_6.5/convert_avh1b.F Accept GAC AVHRR in PFS format, as in NOAA-18 distributed via EUMETCast. Interpolate to 2048 samples, but keep the GAC scan line interval (0.5 sec). M metop-tools/src/bin/admin-main.c Increase precision of obtutc printout M iasi-tools/src/bin/satpos-svm.pl Correction to satpos-svm. This had some (slight) impact on IASI radiances. A iasi-tools/src/bin/iasi-mode.c A iasi-tools/src/bin/iasi-mode.ksh M iasi-tools/src/bin/Makefile Tool to print out the IASI mode: EXTERNAL_CALIBRATION or NORMAL_OPERATION M iasi-tools/src/libeps_iasil1c_6.6/convert_iasi1c.F Fix bug in start/end time header
